[0020] The magnetic force rod 61 is of a telescopic structure.

[0021] The control unit 102 is further electrically connected with a state indication module 104 arranged on the outer surface of the first main rod 1a.

[0022] The emergency lighting module 401 comprises a light emitting unit 401a; the laser ranging module 402 comprises a laser emitter 402a and a receiver 402b; the water quality rapid detection module 403 comprises a detection electrode 403a; the simple life detection module 404 comprises an infrared sensor unit 404a; and the positioning and beacon module 405 comprises a satellite positioning chip 405a and a wireless communication unit 405b.

[0026] When performing normal planning oar, sawing or excavating operations, the tail cap 1d can not be installed to reduce the overall weight of the tool and facilitate carrying and operation. When impact operations such as knocking obstacles, driving in ground stakes or using as a support rod are needed, the tail cap 1d can be screwed onto the end of the rod body, and the flat end face can be used as an impact stress surface to protect the end thread of the main rod from damage.

[0027] Embodiment two: firefighter rope knot making frame The main rod 1 is provided with a text identification layer 13 for indicating various fire rope knots. The text identification layer 13 includes at least one of the following: a double eight knot, a fisherman knot, a Brin knot, a double Brin knot, a rabbit ear knot, a double fisherman knot, a barrel knot, a roll knot, a butterfly knot, a Prussian grab knot, a Kline grab knot, a double knot, an Italian half hitch, a nine knot, and an eight rope joint.

[0028] The supporting device 51 includes two arch-shaped supports 54 arranged in parallel with each other, and the two arch-shaped supports 54 are fixedly connected by three transverse connecting rods 52. A vertical support 53 is fixedly connected above each arch-shaped support 54, and an arc-shaped bracket 56 with an opening facing upward is fixedly arranged at the top of the vertical support 53.

[0029] The embodiment shows the use of the multipurpose fire rescue tool as a firefighter rope knot making frame 5. First, assemble the supporting device 51. Take two arch-shaped supports 54, connect them end to end using three transverse connecting rods 52, and fix them into a stable chassis. A vertical support 53 is fixedly connected above each arch-shaped support 54.

[0030] Subsequently, the three main rods are connected end to end to form a rod body, and the training long rod is horizontally erected on the two vertical supports 53, that is, a stable knot training frame is formed. The firefighter can perform rope training on the long rod. The main rod 1 is printed with a text identification layer 13 for indicating fifteen common fire knots, including a double eight knot, a fisherman knot, etc., to facilitate the firefighter to learn and practice, and effectively improve the speed and proficiency of knot making. All components of the training frame are made of aluminum alloy, and the total weight is light, facilitating movement and deployment.

[0031] Example three: spliced as a boat paddle As shown in Figure 4 , the rescue personnel quickly rotate the first main rod 1a, the second main rod 1b, and the third main rod 1c to form a long rod, and rotate the paddle plate threaded connection part 22 of the boat paddle assembly 2 into the end part. At this time, the present application is combined into a high-strength rescue boat paddle 25. Since the main body is made of titanium alloy, it is light in weight and corrosion-resistant, facilitating long-time rowing. During rowing, if vortex or undercurrent impact is encountered, the strain gauge sensor 103b monitors the bending moment in real time, and the state indication module 104 lights up green to indicate safety; if the rod body is subjected to excessive force due to improper operation, the indicator light turns red and beeps, prompting the rescue personnel to adjust their posture to prevent the rod from breaking.

[0032] When the outboard motor of the rescue boat fails or needs to be manually controlled in a complex water flow area, the firefighter can use the combined boat paddle to row water, providing power for the boat and ensuring that the rescue mission continues. During rowing, the strain gauge sensor 103b arranged on the three main rods monitors the force on the rod body in real time, and the state indication module 104 on the outer surface of the first main rod 1a displays the force state, ensuring the safety of the long rod operation. The main body of the tool is made of titanium alloy, and the paddle plate 21 is made of plastic, which is high in strength, corrosion-resistant, and the total weight is controlled within 7 kg, which is easy to operate.

[0033] Example four: spliced as a saw As shown in Figure 5 , this embodiment shows the use state of the tool as a saw for removing obstacles.

[0034] First, take out the saw assembly 3. Rotate the saw blade connection part 32 at the end of the saw assembly to the internal threaded connection part 11 at one end of the third main rod 1c, so that the saw blade 31 is fixed to the top end of the main rod, forming a complete rescue saw.

[0035] In water rescue, if the trapped personnel is found to be entangled by ropes, fishing nets or branches, firefighters can use this combination saw to quickly saw off the obstacles and implement emergency rescue. The knife saw made of titanium alloy is sharp and strong, and can effectively cut various materials. During sawing, the strain gauge sensor 103b on the main rod monitors the force on the rod body in real time, and the force state is displayed through the state indication module 104 to prevent overload fracture. The overall length of the tool can be adjusted to facilitate operation at different distances and angles.

[0036] Example five: splicing as a shovel This embodiment is provided as shown in Figure 6 The shovel assembly is provided with a shovel 41, one side of which is provided with a sawtooth 44, and the end of the shovel 41 is provided with a shovel connecting part 42, which is a threaded interface and can be matched and connected with the internal threaded connecting part 11.

[0037] This embodiment shows the use state of the tool as a shovel for post-disaster cleanup or fire extinguishing.

[0038] First, the first main rod 1a, the second main rod 1b and the third main rod 1c are threadedly connected in sequence to form an extendable rod body.

[0039] Then, take out the shovel assembly 4. Tighten the shovel connecting part 42 at the end of the shovel assembly to the internal threaded connecting part 11 at one end of the third main rod 1c to form a complete rescue shovel.

[0040] After a flood disaster, the combined shovel can be used to clean up the silt and debris in the road and house. In forest fire rescue, it can also be used to shovel soil to cover the fire source and create a firebreak. The sawtooth 44 on the side of the shovel 41 can be used to cut off the roots of vegetation or entangled debris. During excavation, the strain gauge sensors 103b on the three main rods monitor the force on the rod body in real time, and the force state is displayed through the state indication module 104 of the first main rod 1a to ensure the safety of the operation in deep water or silt environment. By quickly replacing the functional components, the same set of tool body can adapt to various disaster scenes from water to land, realizing the multifunctional integration and efficient use of equipment.

[0041] Example six: strain monitoring and safety warning of main rod force As shown in Figure 1 As shown in Figure 1 This embodiment shows the intelligent monitoring function of the strain gauge sensor 103b. The first main rod 1a, the second main rod 1b and the third main rod 1c are each embedded with a strain gauge sensor 103b, which is in communication connection with the control unit 102 built in the first main rod 1a.

[0042] When the firefighters connect multiple main rods through the internal thread connection 11 and the external thread connection 12 to form an extended rod body, and install the underwater salvage hook claw assembly 5 or the strong magnetic salvage assembly 6 to carry out heavy object salvage operations, or when the iron shovel assembly 4 is used for breaking and excavating, the bending, torsion or tensile stress borne by the main rod will act on the strain gauge sensor 103b in real time. The sensor converts the detected deformation into an electrical signal and transmits it to the control unit 102. After algorithm analysis, the control unit 102 displays the force state of the current rod body in real time through the state indication module 104 arranged on the outer surface of the first main rod 1a, with different colors representing safety (green), criticality (yellow) and overload (red). When the detected stress approaches the material yield strength threshold, the control unit 102 can trigger a buzzer to issue a warning, reminding the firefighters to adjust their operating posture or stop applying force in time to prevent tool overload and breakage, which may cause safety accidents. This function is especially suitable for deep water salvage, ice surface rescue and high-altitude prying and breaking in high-risk scenarios that require long-arm operations, providing real-time safety protection for rescue personnel.

[0043] Example Seven: Strong Magnetic Telescopic Rod Salvaging Metal Objects This example demonstrates the strong magnetic salvage function of the tool. As shown in Figure 7 The firefighters take out the strong magnetic salvage assembly 6, which includes a magnetic rod 61 with a magnetic rod thread connection 62 at the end, and the magnetic rod 61 is a telescopic structure.

[0044] The magnetic rod thread connection 62 is screwed into the internal thread connection 11 at the end of the main rod, forming a strong magnetic salvage rod. According to the salvage depth, the rod body can be extended through the head-to-tail thread connection between the main rods; according to the operating space, the telescopic length of the magnetic rod 61 can be adjusted.

[0045] When metal objects fall into areas where personnel cannot easily access, such as sewers, deep wells, narrow gaps or the bottom of water areas, the firefighters extend the assembled salvage rod into the target area. The front end of the magnetic rod 61 relies on strong magnetic properties to attract metal objects, and then safely removes the objects. During the operation, the strain gauge sensor 103b arranged on the main rod monitors the force state of the rod body in real time, and the force state is displayed through the state indication module 104 arranged on the outer surface of the first main rod 1a, ensuring the safety of the salvage operation. This function is especially suitable for scenarios such as urban waterlogging drainage outlet obstacle removal, evidence salvage and deep well rescue.

[0046] Example Eight: Vertical Rods Combined as Rope Force Support Points This example demonstrates the application of the tool as the core load-bearing component of the rope system. When performing high-altitude rescue, slope dragging or building a temporary tripod, the firefighters take out the first main rod 1a and the second main rod 1b.

[0047] First, the outer threaded connection part 12 at one end of the first main rod 1a is screwed into the inner threaded connection part 11 at one end of the second main rod 1b, so that the two are firmly connected into a whole long rod by threading. Alternatively, according to the needs of the operation, the two main rods can be selected to be in parallel close contact, and the middle section and both ends are tied and fixed with a rope, so as to form a combined force structure.

[0048] Subsequently, according to the site terrain, the connected rod body or parallel double rods are fixed to trees, building columns or anchored to the ground with ground nails in the form of "A" or "H" and the like through a rope. At this time, the main rods 1a, 1b made of titanium alloy form a firm force fulcrum. The rescue rope can be directly wound or suspended on the fulcrum through a pulley for bearing the main load in the traction, lifting or lowering operation.

[0049] During the operation, the strain gauge sensor 103b arranged on the main rod monitors the tension and bending moment of the rod body in real time, and the data is transmitted to the control unit 102 in the first main rod 1a for analysis, and the current stress state is displayed through the state indication module 104 arranged on the outer surface of the first main rod 1a. When the stress is detected to be close to the material yield strength threshold, the control unit 102 triggers a warning to remind the firefighter to adjust or reinforce in time, and the structural strength and intelligent monitoring function are far superior to the use of random branches or railings found on site, greatly improving the safety and reliability of the rope system.

[0050] Example Nine: Underwater salvage hook claw salvages non-metallic articles This embodiment shows the underwater hook claw salvage function of the tool. As shown in Figure 8 , the firefighter takes out the underwater salvage hook claw assembly 5, which includes a hook claw 501 made of nylon material, and a hook claw threaded connection part 503 at the end of the hook claw 501. Screw the hook claw threaded connection part 503 into the inner threaded connection part 11 of the main rod, that is, assemble the salvage rod. When there are non-metallic articles such as fallen clothes, plastic bags, water grass entanglements or evidence bags that need to be salvaged from the water, the firefighter stretches the hook claw 501 to the target object below, hooks the handle, gap, fabric edge, and slowly lifts the article. This function is suitable for cleaning floating objects on the water surface, salvaging fallen evidence, or rescuing people entangled with debris.

[0051] Example Ten: Salvage net assembly salvages scattered or multiple articles This embodiment shows the salvage function of the salvage net assembly 7. As shown in Figure 9 , the salvage net assembly 7 includes a net frame 71 and a net frame threaded connection part 73 arranged at the end of the net frame.

[0052] When it is necessary to salvage a large number of small items scattered on the bottom of the water, such as tool parts, shell casings, evidence fragments, or a large amount of debris, the firefighter screws the net frame threaded connection part 73 into the inner threaded connection part 11 of the main rod to assemble a net bag type salvage rod. The salvage net is extended into the water and slowly swept from the side or below the target area, so that the scattered items enter the net bag of the net frame 71. For items sunk in the mud, the iron shovel assembly 4 can be used to loosen them first, and then the salvage net is used to salvage them. The net bag of the net frame 71 is made of fine mesh material, which can effectively intercept small items to prevent loss. After the salvage is completed, the net bag is lifted to the water surface, and the salvaged items can be collected. This function is especially suitable for underwater evidence search, lost tool recovery, and water area debris cleaning, and other operation scenes that require batch salvage.

[0053] Example Eleven: Rapid Water Quality Detection This example shows the rapid water quality detection function of the tool. As shown in Figure 10 , the firefighter takes out the water quality rapid detection module 403, which is provided with a detection electrode 403a at the bottom and a physical and electrical connection structure matching the standard expansion interface 300 at the top. When the water source in the disaster area is suspected to be contaminated, the water quality rapid detection module 403 is inserted into the standard expansion interface 300, and the detection electrode 403a is immersed in the water, so that the pH value, turbidity and other data can be read on the state indication module 104, providing a basis for drinking water safety.

[0054] The water quality rapid detection module 403 is installed on the standard expansion interface 300 of the first main rod 1a, and the module is electrically connected with the battery 301 and the control unit 102 built in the first main rod 1a. The control unit 102 automatically identifies the module type and starts the detection program.

[0055] When dealing with chemical leakage accidents, post-disaster assessment of drinking water safety, or suspected water pollution, the firefighter holds the main rod and immerses the detection electrode 403a at the front end of the module into the water to be tested. After the detection electrode 403a contacts the water sample, it detects the pH value, conductivity, dissolved oxygen and temperature of the water body in real time. After the detection data is processed by the control unit 102, it is displayed on the display screen of the state indication module 104.

[0056] This function enables the firefighter to complete the on-site rapid risk screening without contacting the water sample, providing a scientific basis for determining the pollution range, selecting drinking water sources, and developing disposal plans, and is especially suitable for scenes such as flood disaster areas, chemical industry parks, and field rescue.

[0057] Example Twelve: On-site Distance Measurement by Laser Ranging Module This example shows the laser ranging function of the tool. As shown in Figure 11As shown, the firefighter takes out the laser ranging module 402, which has a laser transmitter 402a and receiver 402b integrated inside, and a physical and electrical connection structure matching the standard expansion interface 300 on the top.

[0058] The laser ranging module 402 is installed on the standard expansion interface 300 of the first main rod 1a, and the module establishes electrical connection with the built-in battery 301 and control unit 102 of the first main rod 1a. The control unit 102 automatically identifies the module type and activates the ranging function.

[0059] At the rescue site, the firefighter holds the main rod and aims the module at the target, presses the start switch, the laser transmitter 402a emits a laser pulse to the target, the receiver 402b receives the reflected signal, and the control unit 102 accurately calculates the distance according to the speed of light and the time difference. It can be used to measure the width of building cracks, assess the crossing distance of rivers or cliffs, calculate the height of the floor where the trapped person is located, determine the radius of the danger zone, or plan a safe operation channel. The ranging data is displayed in real time on the screen of the status indication module 104, or transmitted to the command terminal through the wireless communication unit 405b of the positioning and beacon module 405, providing reliable data support for accurate rescue decision-making and on-site risk assessment.

[0060] Example XIII: Simple life detection module for heat source search This example demonstrates the simple life detection function of the tool. As shown, Figure 12 The firefighter takes out the simple life detection module 404, which has an infrared sensor unit 404a at the core and a physical and electrical connection structure matching the standard expansion interface 300 on the top.

[0061] The simple life detection module 404 is installed on the standard expansion interface 300 of the first main rod 1a, and the module establishes electrical connection with the built-in battery 301 and control unit 102 of the first main rod 1a. The control unit 102 automatically identifies the module type and activates the detection function.

[0062] In the initial search and rescue at disaster sites such as earthquakes and building collapses, the firefighter holds the main rod and aims the infrared sensor unit 404a at the front end of the module at the gap in the ruins, the rubble pile, or the area behind the obstacle. The infrared sensor unit 404a can sense small temperature changes and identify the body heat source emitted by trapped personnel, and display it in the form of an image or signal strength on the status indication module 104 after processing by the control unit 102.

[0063] Using the extendable feature of the main rod, the firefighter can extend the detection module into narrow gaps or high holes for detection, expanding the search range. When a suspected vital sign signal is detected, the module provides an important clue for determining the approximate location of survivors and narrowing down the key search and rescue area, significantly improving the search and rescue efficiency of the golden rescue time.

[0064] Example 14: Team positioning and communication with beacon module This example demonstrates the positioning and communication function of the tool. The firefighter takes out the positioning and beacon module 405, as shown in the figure. The module is built-in with a satellite positioning chip 405a and a wireless communication unit 405b, and has a connection structure on the top that matches the standard expansion interface 300. Figure 13

[0065] The positioning and beacon module 405 is installed on the standard expansion interface 300 of the first main rod 1a, and the module is electrically connected with the built-in battery 301 and control unit 102 of the first main rod 1a. The control unit 102 automatically identifies the module type and activates the positioning function.

[0066] When performing search and rescue tasks in complex terrain such as mountainous areas, water areas, underground spaces, or inside large buildings, the firefighter turns on this module. The satellite positioning chip 405a obtains accurate position information in real time, and the wireless communication unit 405b sends position data, team number and status information to the rear command center through a dedicated frequency band, and can also share the position as a position beacon among team members. When the team member is in danger or needs assistance, a one-key alarm signal can be sent through the module, and the command center can quickly locate and dispatch the nearest force to rescue. This function solves the problems of team positioning and communication in complex environments, greatly improving the safety and efficiency of team coordination.

[0067] Example 15: Night work lighting with emergency lighting module This example demonstrates the emergency lighting function of the tool. As shown in the figure, the firefighter takes out the emergency lighting module 401, which includes a light-emitting unit 401a and has a physical and electrical connection structure on the top that matches the standard expansion interface 300. Figure 14

[0068] The emergency lighting module 401 is installed on the standard expansion interface 300 of the first main rod 1a, and the module is electrically connected with the built-in battery 301 and control unit 102 of the first main rod 1a. The control unit 102 automatically identifies the module type and activates the lighting function, and the light-emitting unit 401a is immediately turned on.

[0069] In night rescue, underground space operation, tunnel collapse or dimly lit disaster scene, the firefighter can turn this tool into a strong light illuminator. Through the extendable feature of the main rod, the lighting module can be held high for wide-area flood lighting, illuminating the operation area or search path; or the tool can be inverted and fixed with the support device 51 as a fixed lighting source. The module supports multiple brightness adjustment and stroboscopic modes, which can be used for emergency signal warning. This function solves the problem of insufficient lighting in night or dark environments, providing reliable light source support for rescue operations.​​
